The STILLEN Infiniti M37 intake kit replaces the restrictive factory air boxes with 2 dual cone genuine K&N reusable high flow conical air filters. These filters are designed with an integral velocity stack and attach to our newly designed polished aluminum long tubes. Replacing the factory intake tubes with the STILLEN design adds additional horsepower, and a great look for the engine bay. We have also included two paint able urethane heat shields to keep the intake charge as cool as possible.

By installing just the intake kit we have seen a gain of +5 horsepower and +4lb feet of torque at the wheels on our test vehicles. Plus, you getting the added bonus of adding a little grunt to the intake sound of your M37.
